Signal shighting - East Midlands Parkway

This from a Mr Powell...

If there are a spate of SPADs around East Midlands Parkway in coming months, this may be why...


Note the important sign refers to the now non-existent TT415, when the real signal is ST4497!

Does Network Rail know and can't be bothered to sort it, or have they just not noticed yet?

I think we should be told!
